Others have described how to do this but I want to make the point that
it is often a feature that people use when they should not. It is
inefficient and also a potential security hole. Often people use it to
just convert types or delay executiion of some code. I don't know
anything about you so you may be an expert and know exactly what you are
doing but just in case not, I thought I'd give a warning.
